Definitions
- dispensing devices or guns available for dispensing different types of flowable substance which are marketed in cartridges.
- One type of dispensing device is the grease gun which for the purposes of this specification and claims is defined as including a cylinder provided with a dispensing screw cap at a first end and a spring biased plunger at an opposite end.
- the screw dispensing cap is threadingly engaged with the first end of the cylinder and is provided with a lever operated piston valve.
- the spring biased plunger is biased so as to exert force in a direction from the opposite end toward the first end.
- the typical cartridge used for holding grease and for use with this grease gun is in the form of a tubular cartridge which is sealed at both ends by removable end plates and has a lip about one end of the cartridge.
- the lever (or in some cases levers) can then be pumped to create a vacuum which sucks the contents out of the cartridge through the cut nipple. In doing so, the moveable plate at the opposite end of the cartridge slides along an inside wall of the cartridge maintaining a seal.
- the conventional grease cartridge cannot be used in a chalking gun or in a vacuum gun.
- the cartridge used for chalking guns cannot be used in a conventional grease gun.
- a cartridge for holding a supply of a flowable substance said cartridge adapted for use in a plurality of different dispensing devices which can force said substance from said cartridge
- said cartridge including: a hollow elongate body for containing a supply of a flowable substance; a slidable seal fitted inside said body for sealing one end of said body, an opposite end of said body being closed by an integral wall; a sealed nipple formed on said wall and through which said substance can flow when said nipple is cut; a line of weakness formed about said body near said opposite end; and, means protruding radially from an outer circumferential surface of said body and spaced from said opposite end by said line of weakness; wherein, when said cartridge is to be used in a grease gun as hereinbefore defined, said slidable seal can be pulled out of said body and said wall removed by cutting along said line of weakness to allow dispensing of said substance, said flange supporting said cartridge in a cylinder of the grease gun; and when
- said line of weakness comprises a band of reduced thickness formed in the material of said body.
- said band is in the form of a channel having a pair of spaced apart parallel walls and a base extending between said parallel walls.
- said means protruding radially from said outer circumferential surface of said body comprises a flange.
- the flange is formed integrally with the one of the spaced apart walls most distant said nipple.
- said slidable seal is provided with gripping means which a person can manually grip to pull said plate from said body.
- said gripping means comprises a ring formed integrally with said slidable seal.
- the pull ring is attached to one end of a tear strip formed integrally with the slidable seal and adapted to tear away from the slidable seal when the ring is pulled to form a hole in the slidable seal to, expose the inside of the body, between the seal and the substance, to atmospheric pressure.
- said body is provided with a longitudinal extending transparent or translucent strip through which the position of said plate can be viewed.
- Figure 1 is a longitudinal section view through a cartridge in accordance with a first embodiment of the present invention
- Figure la is a front portion of a longitudinal section of a second embodiment of the cartridge.
- the cartridge 10 for holding a supply of a flowable substance such as grease comprises a hollow elongate body in the form of a cylindrical tube 12 which is closed at one end 14 by a slidable seal 16.
- the slidable seal 16 fits inside the tube 12 and forms a seal about its periphery with inside surface 18 of the tube 12.
- the slidable seal 16 is able to slide along the length of the tube 12.
- Means, in the form of a flange 38 is formed about and protrudes radially from the outer circumferential surface the tube 12.
- the flange is near the end wall 22 but spaced therefrom by the channel 30.
- the flange 38 may be immediately adjacent the channel 30 so that the side of the flange nearest wall 22 is coplanar with side wall 32.
- a translucent strip 40 is formed along the length of the tube 12 from end wall 22 to end 14.
- the purpose of the strip 40 is to allow viewing of the position of the slidable seal 16 within the tube 12.
- the slidable seal 16 may be made of a bright colour or at least a contrasting colour to that of the substance held within the tube 12.
- a scale can be marked along the strip 40 to allow measured dispensing of the substance held in the tube 12.
- Slidable seal 16 is typically in the form of a shallow cup having a circumferential side wall 42 which is in sealing contact with the inside surface 18 of tube 12.
- Base 44 of the slidable seal 16 is in the form of a disc formed integrally with the circumferential wall 42.
- the slidable seal 16 is orientated so that the volume of shallow cup is accessible from outside the tube 12.
- a gripping means in the form of a pull ring 46 (refer Figure 2) is formed on the base 44. Pull ring 46 can be attached to one end of a tear strip 48 which is formed integrally with the base 44. An opposite end 50 of the tear strip 48 is fixed to the base 44.
- the trigger actuated plunger of the chalking gun is received by slidable seal 16 and bears against the base 44. By actuation of the trigger the plunger is progressed down the tube 12 pushing the slidable seal 16 with it and thus pushing the substance within the tube 12 out through the nipple 24 and nozzle.
- the channel 30 /line of weakness 28 ensures that the end wall 22 is cut-off square. This will facilitate the easy assembly of the grease gun.
- the flange 38 in this configuration is supported on the end of the cylinder portion of the grease gun which receives the screw dispensing cap thus preventing the tube 12 from dropping any further down. This ensures that once the grease has been dispensed the tube 12 can be easily removed.
- the cartridge 10 is orientated so that the translucent strip 40 is in a position that can be viewed, one will be able to observe the position of the slidable seal 16 within the tube 12. This will allow the user to accurately gauge the amount of substance remaining in the tube 12.
- the flange 38 can be replaced with a plurality of radially extending tabs which provide the same function as the flange 38.
- the translucent strip 40 is not essential to the invention this function can be mimicked by forming the whole of the tube 12 from a translucent or transparent material.
- the pull ring 46 can be dispensed with altogether and/or replaced with another mechanism which allows a slidable seal 16 to be removed from the tube 12.
